Abstract

There are two approaches, HA(Home Agent)-based and FA(Froegn Agent)-based mulicasting in mobile computing environments based on mobile IP. If we consider efficiency of routing and bandwidth the FA-based model is better than the HA-based model. But in the case of a MH(Mobile Host) moves frequently it shows bad connection durability because of join and graph delays. To overcome this and to support effective mobile multicasting we propose an extended FA-based multicast routing. In our model previous FA for wards multicast packets to MH. while new FA processes a jion request from MH. That is in general case our model supports FA-based multicasting for efficiency but it provides unicast-based mulicasting for connection durability when MH moves to new FN(Roreign Network). To evaluate our model, we analyze connecction durability, bandwidth, overheads and routing sosts in many situations and compare with previous works.

Mobile IP 기반의 이동컴퓨팅 환경에서 멀티캐스트를 지원하기 위한 연구는 크게 HA(Home Agent) 기반 모델과 FA(Foreign Agent) 기반 모델로 구분된다. 일반적으로 라우팅 및 대역폭의 효율을 고려한다면, HA 보다는 FA 기반 모델이 효과적이다. 그러나, MH(Mobile Host)의 이동이 빈번할 경우, 가입 및 접합 지연으로 인해 연결 지속성이 떨어지는 단점이 있다. 본 논문에서는 이러한 문제를 해결하고 보다 효과적인 멀티캐스트의 지원을 위해, 확장된 FA 기반 모델을 제안한다. 제안하는 모델에서는 새로운 FA가 가입을 처리하는 동안, MH는 이전의 FA로부터 멀티캐스트 패킷을 수신한다. 즉, 기본적으로는 효율을 위해 FA에 기반해서 멀티캐스트를 지원하지만, MH가 새로운 FN(Foreign Network)으로 이동하는 경우엔 부분적으로 유니캐스트 방안을 적용하여 연결성을 향상시킨다. 제안한 모델을 평가하기 위해 연결 지속성, 대역폭 이용률, 오버헤드 및 라우팅 비용 측면에서 효율을 분석하고 기존의 연구와 비교한다.
